Description

Technical Field

[0001] This utility model belongs to the field of roll paper cutting and fixing fixtures, and particularly relates to a roll paper quantitative cutting device. Background Technology

[0002] In small and medium-sized enterprises, the cutting of paper rolls relies on manual fixing, followed by cutting with a high-speed rotating blade. This method is not only inefficient, but also prone to operator fatigue during long production runs, potentially leading to irreversible safety accidents. Furthermore, the placement of the paper rolls manually may not be aligned with the cutting station, causing the cut surface to be tilted and resulting in defective products. In addition, manual fixing means that only one section can be cut at a time, leading to low efficiency.

[0003] For example, a Chinese utility model patent discloses a roll paper cutting machine device [application number CN201721879391.4], which includes a worktable and a spring. The worktable is provided with a groove that is slidably connected to the cutting table. The output shaft of the first cylinder is fixedly connected to the cutting table. The left side of the cutting table is provided with a second cylinder that is fixedly connected to it, and the right side of the cylinder is provided with a hinged base plate. The cutting table is provided with a cutting groove above it. The right end of the sliding plate is fixedly connected with a telescopic rod. One end of the spring is connected to the base plate, and the other end is connected to the support plate. The upper end of the motor plate is fixedly connected with a motor, and the output shaft of the motor is provided with a cutting blade. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A roll paper quantitative cutting device includes a base, on which several placement blocks are slidably connected. A horizontal shaft is provided above the base, and several cutting devices are slidably connected on the horizontal shaft. The horizontal shaft is connected to a lifting drive device. Each cutting device is provided with a cutting table that can move along a vertical direction. A cutting blade is rotatably provided on the cutting table. The cutting device is also provided with a clamping structure.

[0006] In the aforementioned roll paper quantitative cutting device, the cutting device includes a first side block and a second side block, a cutting cavity is provided between the first side block and the second side block, the cutting table is slidably disposed in the cutting cavity, the second side block is provided with a lifting cavity communicating with the cutting cavity, the cutting table extends into the lifting cavity, a lifting motor is provided on the second side block, and the output shaft of the lifting motor extends into the lifting cavity and is screwed to the cutting table.

[0007] In the aforementioned roll paper quantitative cutting device, the clamping structure includes two extension rods disposed on the first side block. The extension rods extend downward out of the first side block and have an arc clamping rod at their bottom ends. An opposing motion structure disposed on the first side block connects the two extension rods.

[0008] In the aforementioned roll paper quantitative cutting device, the opposing motion structure includes a drive toothed disc rotatably mounted on a first side block, with transverse racks sliding on the first side block respectively meshing at the upper and lower ends of the drive toothed disc, and two extension rods fixedly connected to the two transverse racks respectively.

[0009] In the aforementioned roll paper quantitative cutting device, the inner outer surface of the extension rod is covered with a rubber layer with deformable capabilities.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment provides a roll paper quantitative cutting device, combined with Figure 1-3 As shown, the device includes a base 10, on which several placement blocks 11 are slidably connected. A horizontal shaft 12 is provided above the base 10, and several cutting devices 13 are slidably connected on the horizontal shaft 12. The horizontal shaft 12 is connected to a lifting drive device. The cutting device 13 is provided with a cutting table 14 that can move along the vertical direction. A cutting blade 32 is rotatably provided on the cutting table 14. The cutting device 13 is also provided with a clamping structure 15.

[0020] In this embodiment, the driving power supply for the cutting blade 32 is located inside the cutting table 14. The roll of paper is placed on the placement block 11 of the base 10, and the height of the roll of paper is raised by the thickness of the placement block 11, leaving a cutting gap during the cutting process. After the roll of paper is placed, the distance between the placement blocks 11 is adjusted by moving the placement blocks 11, and the cutting device 13 is moved to adjust the cutting position. Under the action of the lifting drive device, the cutting device 13 moves downward, so that the clamping structure 15 is located on both sides of the roll of paper and clamps the roll of paper, so that the roll of paper remains stable during the cutting process. Then, the roll of paper is cut by the downward movement of the cutting table 14 in conjunction with the continuous rotation of the cutting blade 32. After cutting, the roll of paper is still placed on the placement block 11 to prevent the roll of paper from jumping and causing cutting wear. The movement of the cutting device 13 makes each section of the roll of paper obtain the specified length.

[0021] The cutting device 13 includes a first side block 16 and a second side block 17. A cutting cavity 18 is provided between the first side block 16 and the second side block 17. A cutting table 14 is slidably disposed in the cutting cavity 18. A lifting cavity 19 communicating with the cutting cavity 18 is provided in the second side block 17. The cutting table 14 extends into the lifting cavity 19. A lifting motor 20 is provided on the second side block 17. The output shaft of the lifting motor 20 extends into the lifting cavity 19 and is screwed to the cutting table 14.

[0022] In this embodiment, during the cutting process, the cutting table 14 moves slowly downward at a steady speed through the operation of the lifting motor 20, which is connected to the output shaft of the cutting table 14 by screwing the cutting table 14, so that the cutting blade 32 cuts the roll of paper.

[0023] The clamping structure 15 includes two extension rods 21 disposed on the first side block 16. The extension rods 21 extend downward out of the first side block 16 and have an arc clamping rod 22 at their bottom ends. The two extension rods 21 are connected by an opposing motion structure 23 disposed on the first side block 16.

[0024] In this embodiment, the cutting device 13 moves downward under the action of the lifting drive device, so that the clamping structure 15 is located on both sides of the roll paper. At this time, the arc clamping rods 22 are located on both sides of the roll paper. Then, the two arc clamping rods 22 move closer to each other through the operation of the opposing movement structure 23, thereby clamping the roll paper and fixing it.

[0025] The opposing motion structure 23 includes a drive gear disk 24 rotatably mounted on the first side block 16. The upper and lower ends of the drive gear disk 24 are respectively meshed with transverse racks 25 sliding on the first side block 16, and two extension rods 21 are respectively fixedly connected to the two transverse racks 25.

[0026] In this embodiment, during the process of the arc clamping rod 22 fixing the roll of paper, the drive toothed disc 24 rotates under the action of its motor, thereby causing the transverse rack 25 to move towards each other and at the same speed through meshing, so that the two arc clamping rods 22 fix the roll of paper.

[0027] The inner outer surface of the extension rod 21 is covered with a rubber layer that has the ability to deform.

[0028] In this embodiment, on the one hand, the rubber layer prevents wear on the roll paper, and on the other hand, it increases the friction between the rubber layer and the roll paper to improve the stability of the fixation.

[0029] The base 10 has sliding grooves 26 on both sides, and the two sides of the placement block 11 extend into the sliding grooves 26 and are slidably connected to them.

[0030] In this embodiment, the sliding groove 26 prevents the cutting surface of the roll paper from moving due to the jumping of the placement block 11 during the cutting process.

[0031] The top of the placement block 11 is provided with a curved cover plate 27, and a roll paper placement space 28 is provided between the placement block 11 and the curved cover plate 27.

[0032] In this embodiment, the roll of paper is inserted into the roll placement space 28, and the curved cover plate 27 restricts the movement of the cut surface of the roll of paper caused by jumping when cutting an overly heavy roll of paper.

[0033] The base 10 has an end abutment 29 and an end abutment 30 at its two ends, respectively. The upper surface of the end abutment 30 is flush with the placement surface of the roll paper placement space 28.

[0034] In this embodiment, the two ends of the roll of paper abut against the end abutment piece 29 and the end abutment block 30 to prevent the cut surface of the roll of paper from moving due to jumping or moving during the cutting process.

[0035] One of the end tabs 29 is detachably connected to the base 10 via a vertical slot 31. In this embodiment, when placing the roll of paper, the end tab 29 is removed, the roll of paper is inserted, and then the end tab 29 is inserted back in.
